Will I need a snubber circuit I found an old cut sheet for the cr9321-aca that showed a 2k ohm resistor and a .1uf capacitor as a recommended snubber. When I tried this it made the relay coil hum. The operation in either case was the same. Do I need the snubber to protect the current switch Thanks

We currently use the 936 Series from AAC which specifies 500V/uS voltage tolerance. Is there a spec for the CR5200 Thank you.

The spec sheet says frequency response to 200KHz. I need to know how the current transformer would respond to a 0 to 100 amp step in current. What would be the delay and rise time of the output signal Ideally a graph similar to what is on opamp datasheets would be great. Thanks, Dave Gustavson

The non-mounting case version CR9580-10 has a much shorter lead time.

I have read through the relevant application document and still have a question about the operation of the output function (I am currently basing my design on use of a relay output). In my design, a PLC (installed in an instrument house in the field) receives a call for heat from a central office and in response energizes an output which turns on a heater control case (located...
